CLEANING-POWDER.

Patented Dec. 31, 1912.

To all whom it may concern Be it known that I, EDWIN W. OLDHAM, a citizen of the United States, residing at Canton, in the county of Stark and State of Oh1o have invented a certain new and useful Cleaning-Powder, of which the following is a speclfication.

' he natural water sup 1y used by many cities contains certain 0850111111 salts either with or without iron salts, which gradually make an unsightly deposit in the porcelain water closet bowls and other similar vessels wherein the water is used; and the object of the resent invention is to grovide a dry pow er which, when moistene or applied in 'the presence of water, Wlll remove such deposits without injuring the vessel, and without any inconvenience or dan er to the erson applying the powder. T e remova of such deposits by hydrochloric acid or other like liquids, is lrritatin because of the ob-' noxious vapors constant y given off from the solution, and also, when too much of the acid is inadvertently or i orantl used, is damaging to the vessel y attac ing the porcelain coating and is dangerous to the user by reason of its strength. These difiiculties are avoided and the object of. the invention is attaine by mixing from two to four parts, preferably about three parts, of finely granuated or owdered sodium blsulfate with one .part of Kiln-dried sodium chlorid, likewise granulated, which forms a composition which may be readily and convenientl handled and which will accomplish the d esired results, and will become active only in the presence of moisture or water.

In use, the bowl is first flushed so that the entire surface thereof to be cleaned is wet,

40 and, after the flushing has ceased, a small quantity of the powdered composition is poured or sprinkled into such water as there.

may remain in the bowl and also upon the inside surface of the bowl above the water line. The sodium bisulfatein conjunction with the sodium chlorid dissolves more lime than the bisulfate does when used alone.

The increased solubility resultin from the use of the sodium chlorid in combination with the sodium bisulfate, is no doubt caused by the fact that the presence of the sodium chlorid increases the solubilit in water of the calcium sulfate which is f rmed by the action of the sodium bisulfate upon the calcium carbonate present in the coatin The deposit which remains in the bowl a er the use and action of the cleaning powder is readily removed by again flushing the bowl, accompanied, if necessary, by a slight rub bing of the inner surface thereof.

It is not intended to limit the scope of the invention to the particular proportions of the ingredients set forth, nor to the use of the particular ingredients without the presence of other elements; for it will be understood that the exact pro ortions of the ingredients may be modi ed to correspond with varying conditions, and the resent inventor believes himself to be the rst one to include sodium bisulfate and sodium, chlorid in a cleaning owder and to thereby accomplisli the resu t set forth.

I claim: A cleanin powder includm a mixture of sodium bisu fate and sodium 0 orid.

EDWIN w. QLDHAM.
